I don't have any artistic talent so just picture my ideas.

Based on description.

Festive 2014 skins; Grinchy Aatrox - He's green and red, fuzzy and instead of a sword, he will be using a chsitmas tree. Every time he swings it, decorations spill out and get thrown around. While reviving from his passive, the golden star falls down onto him (Like Anivias passive animation) and he screams "THE SPIRIT OF CHRISTMAS CAN'T STOP ME!" Ugly Sweater Rengar - He's wearing a really ugly holiday sweater and he's angry about it. It's itchy, so every couple of seconds his standing animation would be him scratching his body. H'e also got some christmas lights wrapped around his braids. His claws are sharpened Candy Canes. Winter Soldier Azir - He's white, and replaces sand with snow/frost. His soldiers would be Snow Golems with carrots for spears.

Miscellaneous; Hillbilly Sejuani - She's dressed as a hillbilly country girl riding a giant pink pig. For the effects, I really have no idea. Swamp water? Don't know about the ultimate. Paladin Hecarim - Brown horse on the lower half. Upper half covered with bright white shiny armor with a light spear. He would talk proper and in a medieval tone. "m'lady!" DONGER 3000 - It's a cyborg Heimerdinger with space aged turrets, missles and grenades. It'll be looking almost like Nunubot in terms of skin texture and voice acting. Chief Draven - Native American all painted up and clothed into the Chief leader position, throwing Tomahawks. He speaks like an early Native American, too.

That's all for now.
